BITMAPFILEHEADER structure (wingdi.h)
The BITMAPFILEHEADER structure contains information about the type, size, and layout of a file that contains a DIB.
Syntax
typedef struct tagBITMAPFILEHEADER {
WORD bfType;
DWORD bfSize;
WORD bfReserved1;
WORD bfReserved2;
DWORD bfOffBits;
} BITMAPFILEHEADER, *LPBITMAPFILEHEADER, *PBITMAPFILEHEADER;
Members
bfType
The file type; must be 0x4d42 (the ASCII string "BM").
bfSize
The size, in bytes, of the bitmap file.
bfReserved1
Reserved; must be zero.
bfReserved2
Reserved; must be zero.
bfOffBits
The offset, in bytes, from the beginning of the BITMAPFILEHEADER structure to the bitmap bits.
Remarks
A BITMAPINFO or BITMAPCOREINFO structure immediately follows the BITMAPFILEHEADER structure in the DIB file. For more information, see Bitmap Storage.
Examples
